Adjustable Maximum Current Output to Support Multiple Circuit Ratings
The GRIZZL-E ™ charging station product features the ability to adjust the maximum Charging
Station current output to allow the use of a 50A, 40A, 30A, or 20A Dedicated Circuit as follows:
50A Circuit Rating: To support 40A (9.6 kW) maximum Charging Station output
40A Circuit Rating: To support 32A (7.68 kW) maximum Charging Station output
30A Circuit Rating: To support 24A (5.76 kW) maximum Charging Station output
20A Circuit Rating: To support 16A (3.84 kW) maximum Charging Station output
Notes on Circuit Requirements and Amperage settings:
• The Charging Station Default Factory Maximum Current Output Setting is 40A (9.6 kW) for
use with a 50A Circuit Rating – Please refer to Adjusting Maximum Current Output on page
12 when using a 40A or 30A or 20A Circuit Rating.
5

• To obtain the fastest charging capability of 40A, a 50A Circuit Rating must be used.
• The Circuit must be a DEDICATED CIRCUIT 208-240 VAC, 50-60 Hz, Single Phase.
• Per only 80% of the circuit rated load may be utilized, hence the higher Circuit Ratings
Requirement relative to maximum Charging Station output.
• Temporary error condition include: Overcurrent, Overvoltage, Undervoltage, Missing diode,
Ground fault and Over Temperature.
• For Over Current (OC) conditions: The charging session will be stopped while OC occurs.
After recovery from OC for 30 seconds, the charging station will automatically restart charging
for 4 times.
• When charging session stopped due to Ground Fault (GFCI) trip, the charging station will
try to restart after 15 minutes for 4 times. After 4 times, the charging station buzzer will stay
on continuously, and status indicator will stay RED. The user should plug-out and plug-in the
power cable of the charging station.
The ability to utilize alternate circuit ratings can be beneficial in the instance the location
of installation cannot support a 50A circuit, or in instance where an existing 40A
or 30A or 20A dedicated circuit is already installed.
Security and Tamper Feature
Self-Monitoring and Recovery | Power Outage Recovery
In addition to the pin that secures the GRIZZL-E ™ charging station to the wall mount bracket
(Refer to Section 2.3, Paragraph 3., Installing the Charging Station), if desired, a feature is
included as part of the charging station and wall mount bracket to replace provided pin with
the coupler lock with the minimum parameters:
Length: 90mm, Diameter: 7mm
for added security and tamper benefits.
When a charging session is interrupted due to a temporary error condition, the charging
station will automatically restart charging when the cause of the temporary error condition
returns to normal. The status indicator lights remain flashing RED until the error condition
is resolved.

2. INSTALLATION
2.1 Before Installation
2.1.1 Installation Planning & Service Wiring
• Do not touch live electrical parts.
• Incorrect connections may cause electric shock.
• Disconnect the power supply to the charging station and verify no power is present before
installing, adjusting, or repairing the charging station. Failure to do so may result in physical
injury or damage to the power supply system and the charging station.
The charging station must be installed only by a licensed electrician in accordance with the
provisions of the local electrical industry construction and should comply with national
electrical codes and standards.
Before installing the charging station, make sure you have read these instructions in this
manual and fully understand its contents.
Appropriate protection is required when connecting to a main panel/switchboard. The tools
and parts used as outlined in the section “Tools & parts required for installation”.
Prior to mounting, determine location of an acceptable mounting support. All charging
station products must be anchored into a mounting support such as a 2” x 4” stud or a solid
concrete wall, using mounting hardware that is appropriate for the surface on which you are
mounting. DO NOT mount this unit directly to a stucco/drywall/wall board. If installing to a
wood stud, use the lag screws provided and ensure the mounting plate is positioned on the
centerline of the stud. If mounting onto a concrete, block, or brick wall, use an appropriate
anchor for the type of wall on which you are installing the unit.
Prior to mounting, locate an available electrical source that can support the following Input
Requirements for the Charging Station Per local Electrical Safety Code requirements:
• 40A Maximum Output Setting (Default Factory Setting): a DEDICATED CIRCUIT rated for
50A; 208-240 VAC, 50-60 Hz, Single Phase must be used.
• 32A Maximum Output Setting (Optional Setting): a DEDICATED CIRCUIT rated for 40A;
208-240 VAC, 50-60 Hz, Single Phase must be used.
• 24A Maximum Output Setting (Optional Setting): a DEDICATED CIRCUIT rated for 30A;
208-240 VAC, 50-60 Hz, Single Phase must be used.
• 16A Maximum Output Setting (Optional Setting): a DEDICATED CIRCUIT rated for 20A;
208-240 VAC, 50-60 Hz, Single Phase must be used.
Note: Please refer to Adjusting Maximum Current Output on page 12.
Warning: risk of electric shock
11

• Additionally, a Double Pole Circuit Breaker of the circuit rating must be used. The Charging
Unit has a built in GFCI protection; do not provide any additional GFCI protection upstream of
the charging unit.
• The Charging Stations can connect (plug into) a Standard NEMA 6-50 or 14-50 Receptacle or
the unit can be hardwired
Caution:
The service wiring in this section are specific to North America only. Before installing
the Charging Station, identify the type of utility service connection available onsite. If
you are unsure about the type of connection available at the service panel, contact
your utility service provider.
2.1.2 Grounding Instructions
2.1.3 Adjusting the Charging Station Maximum Current Output
Setting (Optional)
The charging station must be implemented equipment grounding through a permanent
wiring system or an equipment grounding conductor. Use a cable with a dedicated grounding
conductor connected to the equipment ground terminal block.
• Do not touch live electrical parts.
• Incorrect connections may cause electric shock.
• Disconnect the power supply to the charging station and verify no power is present before
installing, adjusting, or repairing the charging station. Failure to do so may result in physical
injury or damage to the power supply system and the charging station.
• Electrical Power MUST remain OFF and DISCONNECTED before setting or changing the DIP
switch. A non-conductive object MUST be used to adjust the DIP switch settings, failure to do
so may result in risk of electrical shock and damage to the equipment.
The GRIZZL-E ™ charging station product features the ability to adjust the maximum Charging
Station current output to allow the use of a 50A, 40, 30A, or 20A Dedicated Circuit as follows:
Warning: risk of electric shock
50A Circuit Rating: To support 40A (9.6 kW) maximum Charging Station output
40A Circuit Rating: To support 32A (7.68 kW) maximum Charging Station output
12

30A Circuit Rating: To support 24A (5.76 kW) maximum Charging Station output
20A Circuit Rating: To support 16A (3.84 kW) maximum Charging Station output
The Charging Station Default Factory Maximum Current Output Setting is 40A (9.6 kW) for use
with a 50A Circuit Rating. To adjust the Maximum Current Output Setting when using a 40A or
30A or 20A Circuit Rating:
1. Place the Charging Station on a flat surface, front cover up.
2. Remove the Charing Station front cover by loosening the (4) Cap screws at each corner of the
charging station.
Figure 2-1. Four screws locations to remove the Charging Station Cover.
3. With the front cover placed to the side, locate the DIP switch on the charging station circuit
board. The DIP switch is a 3-position switch on the main circuit board, located directly to the
left of the LED.
Caution:
The LED pipe is attached to the charging station front cover. When front cover is
removed, place the front cover on the surface with front cover down and LED pipe
up. Placing front cover on LED pipe might damage or break LED pipe.
